Methods
Using the Mie theory of scattering for homogeneous spheres , the low-angle and
high-angle light scatter signals for each cell are transformed into volume and
hemoglobin concentration values. RBCs have cell volumes between 30 fL and
180 fL, and hemoglobin concentrations between 19 g/dL and 49 g/dL.
